Description

Technical Field

[0001] This invention relates to the field of electroplating product clamping technology, specifically a double-layer staggered dynamic gripper electroplating fixture. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the manufacturing process requirements for its parts are also increasing. In the production process of new energy vehicle parts, electroplating is crucial for improving the corrosion resistance, wear resistance and aesthetics of the parts. However, most fixtures have problems such as material leakage and exposed substrate.

[0003] In existing technologies, two sets of clamps are used to alternately hold the parts to prevent the introduction and leakage of substrate material. However, there are still some shortcomings. For example, during the electroplating process, bubbles are easily generated on the surface of the parts. If these bubbles are not removed in time, they will affect the quality of the electroplating layer, leading to a decrease in the corrosion resistance of the parts and defects such as pitting on the surface. At the same time, existing clamps lack effective control over the flow of electrolyte and cannot ensure precise impact on the surface of the parts during defoaming, thus affecting the overall electroplating effect. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a double-layered staggered dynamic gripper electroplating fixture.

An alternating clamping mechanism is used to switch the action on the parts, and the alternating clamping mechanism is disposed inside the sleeve; And a flow guiding mechanism, which can enhance the effect of bubble removal, is provided within the alternating clamping mechanism.

[0006] As a further description of the above technical solution: the alternating clamping mechanism includes a rotating shaft, a lever fixedly connected to the outer wall of the rotating shaft, a movable block movably disposed inside the bottom end of the sleeve, a driving frame provided on the bottom side of the movable block, a lifting rod slidably disposed on one side wall of the driving frame, a spring fixedly connected to one end of the lifting rod and the sleeve, trapezoidal blocks abutting on two opposite sides of the bottom end of the driving frame, a moving rod fixedly connected to the bottom end of the trapezoidal blocks, and insertion plates slidably disposed on the opposite ends of the two trapezoidal blocks, the insertion plates being away from... One end of the trapezoidal block is fixedly connected to an insertion rod. A placement groove is provided inside the sleeve. The upper end of the insertion rod is slidably disposed in the placement groove. A retaining block is movably sleeved on the outside of the insertion rod. A spring is fixedly connected between the retaining block and the insertion plate. Both the retaining block and the insertion plate are horizontally slidably disposed inside the sleeve. The upper end of the retaining block abuts against the trapezoidal plate. The upper end of the trapezoidal plate extends into the cavity of the sleeve. One side of the lever is movably inserted into the counterweight block on the outer wall of the rotating shaft. The two opposite interiors of the bottom end of the drive frame abut against the trapezoidal blocks on both sides.

[0007] As a further description of the above technical solution: the flow guiding mechanism includes a first flow guiding plate and a second flow guiding plate. The first flow guiding plate and the second flow guiding plate are disposed on two opposite sides of the bottom end of the moving rod. The first flow guiding plate is perpendicular to the moving rod, and the second flow guiding plate is inclined. A rotating rod is fixedly connected to the upper end of both the first flow guiding plate and the second flow guiding plate. A torsion spring is fixedly connected between the outer wall of the rotating rod and the moving rod. A connecting magnetic block is fixedly connected to the outer wall of the upper end of the rotating rod. Fixed magnetic blocks are provided on opposite sides of the connecting magnetic blocks on both sides. The fixed magnetic blocks are fixedly connected inside the sleeve.

[0008] As a further description of the above technical solution: a non-Newtonian fluid is placed in the placement groove.

[0009] As a further description of the above technical solution: one end of the movable block is provided with a slope one, and the other opposite end of the movable block is provided with a slope two.

[0010] As a further description of the above technical solution: four movable blocks are provided at equal intervals along the length of the sleeve, two of which are fixed to the upper end of the drive frame, and the other two drive frames are horizontally slidably disposed on the upper end of the drive frame. The connection methods between adjacent movable blocks and drive frames are different.

[0013] This invention provides an improved double-layer staggered dynamic gripper electroplating fixture, which has the following improvements and advantages compared with the prior art: Firstly, the alternating clamping prevents plating leakage and ensures full electroplating coverage. Through the cooperation of staggered paddles and four sets of movable blocks with different connection methods, when the motor rotates clockwise, the paddles press the inclined surface of the movable block, driving the moving rod to achieve alternating clamping and releasing, allowing the clamping parts of the parts to be exposed in turn, completely avoiding the exposure of the substrate. The inclined surface design of the movable block and the elastic return of the second spring make the clamping switching smooth, which not only meets the high-precision electroplating requirements of new energy vehicle parts, but also avoids damage to the parts. Secondly, efficient defoaming improves quality, resulting in a uniform and defect-free coating. The motor rotates counterclockwise at high speed to trigger oscillation defoaming. The non-Newtonian fluid prevents the trapezoidal block from moving laterally, and the counterweight increases the clamping force due to centrifugal force, ensuring that the parts do not fall off during oscillation. The flow guiding mechanism uses magnetic repulsion to switch the state of the flow guiding plate, guiding the electrolyte to accurately impact the surface of the parts and the clamping blind area, dispersing accumulated bubbles, reducing pitting defects, and significantly improving the corrosion resistance and smoothness of the coating. Thirdly, the integrated functions are stable and cost-effective, adaptable to the needs of multiple processes. The alternating clamping and defoaming functions can be achieved simply by rotating the motor forward and backward, without the need for additional drive equipment. This simplifies the structure, reduces energy consumption, and the clamping force can be automatically adjusted according to the working conditions. During alternating clamping, the appropriate force is maintained to prevent damage, and the stability is automatically enhanced during defoaming. The guide plate reduces resistance vertically when not oscillating. The two functions can be performed intermittently, adaptable to multiple processes such as electroplating and pre- and post-cleaning, and improves production efficiency. In summary, alternating clamping prevents plating leaks. Through the coordination of staggered levers and multiple sets of movable blocks, the grippers alternately clamp parts, effectively avoiding substrate leaks and ensuring complete electroplating coverage. Highly efficient defoaming improves quality; the oscillation function combined with a flow guiding mechanism precisely impacts the part surface and clamping area, dispersing plating bubbles, reducing pitting defects, and improving the corrosion resistance and surface quality of the plating layer. Integrated functions ensure stability and cost-effectiveness; a single motor can switch between alternating clamping and defoaming functions to adapt to different processes; non-Newtonian fluid and counterweight design enhance clamping stability while reducing operating resistance and cost.

[0016] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Please see Figure 1 - Figure 8 This invention provides a technical solution: a double-layer staggered dynamic gripper electroplating fixture, comprising an electroplating tank 1, with electric push rods 2 on both opposite outer sides of the electroplating tank 1, connecting blocks 4 fixedly connected to the extended ends of the electric push rods 2, sleeves 6 fixedly connected to the opposite ends of the connecting blocks 4 on both sides, and a motor 5 fixedly connected to the side of one of the connecting blocks 4, and further comprising: The rotating shaft 31 is used to drive the component to rotate to alternately clamp the parts. The rotating shaft 31 is rotatably set inside the sleeve 6, and one end of the rotating shaft 31 is fixedly connected to the output end of the motor 5. Alternating clamping mechanism 3 is used to switch the action on the parts, and alternating clamping mechanism 3 is set inside sleeve 6; And the flow guiding mechanism 7 can enhance the effect of bubble removal. The flow guiding mechanism 7 is set in the alternating clamping mechanism 3.

[0018] Specifically, alternating clamping prevents plating leakage and ensures full electroplating coverage. Through the staggered arrangement of the paddle 32 and the cooperation of four sets of movable blocks 34 with different connection methods, when the motor 5 rotates clockwise, the paddle 32 presses the inclined surface 315 of the movable block 34, driving the moving rod 33 to achieve alternating clamping with "one clamp and one release", allowing the clamping parts of the parts to be exposed in turn, completely avoiding the exposure of the substrate. The inclined surface design of the movable block 34 and the elastic return of the second spring 313 make the clamping switching smooth, which not only meets the high-precision electroplating requirements of new energy vehicle parts, but also avoids damage to the parts. High-efficiency defoaming improves quality, resulting in a uniform and defect-free coating. The motor 5 rotates counterclockwise at high speed to trigger oscillation defoaming. Non-Newtonian fluid prevents the trapezoidal block 37 from moving laterally. The counterweight 35 is subjected to centrifugal force to increase the clamping force, ensuring that the parts do not fall off during oscillation. The flow guiding mechanism 7 uses magnetic repulsion to switch the state of the flow guiding plate, guiding the electrolyte to accurately impact the surface of the parts and the clamping blind area, dispersing the accumulated bubbles, reducing pitting defects, and significantly improving the corrosion resistance and smoothness of the coating. The integrated functions are stable and cost-effective, adaptable to multiple process requirements. Only 5 forward and reverse rotations of the motor are needed to achieve the dual functions of alternating clamping and defoaming. No additional drive equipment is required, simplifying the structure and reducing energy consumption. The clamping force can be automatically adjusted according to the working conditions. When alternating clamping, it maintains appropriate force to prevent damage. When defoaming, it automatically enhances stability. When the guide plate is not oscillating, it vertically reduces resistance. The two functions can be performed intermittently, adapting to multiple processes such as electroplating and pre- and post-cleaning, improving production efficiency.

[0019] In another embodiment of the present invention, the alternating clamping mechanism 3 includes a rotating shaft 31, a lever 32 fixedly connected to the outer wall of the rotating shaft 31, a movable block 34 movably disposed inside the bottom end of the sleeve 6, a driving frame 314 provided on the bottom side of the movable block 34, a lifting rod 317 slidably disposed on one side wall of the driving frame 314, a spring 313 fixedly connected between one end of the lifting rod 317 and the sleeve 6, trapezoidal blocks 37 abutting on two opposite sides of the bottom end of the driving frame 314, a moving rod 33 fixedly connected to the bottom end of the trapezoidal blocks 37, and an insertion plate 38 slidably disposed on the opposite ends of the two trapezoidal blocks 37, the insertion plate 38 being away from the trapezoidal blocks 37. One end of the sleeve 6 is fixedly connected to a rod 39. A placement groove 310 is provided inside the sleeve 6. The upper end of the rod 39 is slidably disposed in the placement groove 310. A retaining block 312 is movably sleeved on the outside of the rod 39. A spring 311 is fixedly connected between the retaining block 312 and the insertion plate 38. Both the retaining block 312 and the insertion plate 38 are horizontally slidably disposed inside the sleeve 6. The upper end of the retaining block 312 abuts against the trapezoidal plate 36. The upper end of the trapezoidal plate 36 extends into the cavity of the sleeve 6. One side of the lever 32 is movably inserted into the counterweight 35 on the outer wall of the rotating shaft 31, which drives the bottom of the frame 314 to abut against the trapezoidal blocks 37 on both sides.

[0020] A non-Newtonian fluid is placed in the placement tank 310.

[0021] One end of the movable block 34 has a slope 315, and the other opposite end of the movable block 34 has a slope 316.

[0022] Four movable blocks 34 are provided at equal intervals along the length of the sleeve 6. Two of the movable blocks 34 are fixed to the upper end of the drive frame 314, and the other two drive frames 314 are horizontally slidably disposed on the upper end of the drive frame 314. The connection methods between adjacent movable blocks 34 and drive frames 314 are different.

[0023] Adjacent toggle blocks are staggered in phase 32.

[0024] Specifically, alternating clamping prevents plating leaks and ensures full plating coverage. Through the staggered arrangement of the toggle block 32 and the cooperation of four sets of movable blocks 34 with different connection methods, when the motor 5 rotates clockwise, the toggle block 32 presses the inclined surface 315 of the movable block 34, driving the moving rod 33 to achieve alternating clamping with "one clamp and one release". This allows the clamping parts of the parts to be exposed in turn, completely avoiding the exposure of the substrate. The inclined surface design of the movable block 34 and the elastic reset of the spring 313 make the clamping switching smooth, which not only meets the high-precision electroplating requirements of new energy vehicle parts, but also avoids damage to the parts.

[0025] In another embodiment of the present invention, the flow guiding mechanism 7 includes a first flow guiding plate 71 and a second flow guiding plate 72. The first flow guiding plate 71 and the second flow guiding plate 72 are disposed on two opposite sides of the bottom end of the moving rod 33. The first flow guiding plate 71 is perpendicular to the moving rod 33, and the second flow guiding plate 72 is inclined. A rotating rod 73 is fixedly connected to the upper end of both the first flow guiding plate 71 and the second flow guiding plate 72. A torsion spring 76 is fixedly connected between the outer wall of the rotating rod 73 and the moving rod 33. A connecting magnetic block 74 is fixedly connected to the upper outer wall of the rotating rod 73. Fixed magnetic blocks 75 are provided on the opposite sides of the connecting magnetic blocks 74 on both sides. The fixed magnetic blocks 75 are fixedly connected inside the sleeve 6.

[0026] The end of the connecting magnetic block 74 that is close to the fixed magnetic block 75 repels the fixed magnetic block 75. When the rotating rod 73 rotates to its maximum amplitude, the first guide plate 71 and the second guide plate 72 are tilted relative to the bottom of the moving rod 33.

[0027] Specifically, efficient defoaming improves quality, resulting in a uniform and defect-free coating. The motor 5 rotates counterclockwise at high speed to trigger oscillation defoaming. Non-Newtonian fluid prevents the trapezoidal block 37 from moving laterally. The counterweight 35 is subjected to centrifugal force to increase the clamping force, ensuring that the parts do not fall off during oscillation. The flow guiding mechanism 7 uses magnetic repulsion to switch the state of the flow guiding plate, guiding the electrolyte to accurately impact the surface of the parts and the clamping blind area, dispersing accumulated bubbles, reducing pitting defects, and significantly improving the corrosion resistance and smoothness of the coating. The integrated functions are stable and cost-effective, adaptable to multiple process requirements. Only 5 forward and reverse rotations of the motor are needed to achieve the dual functions of alternating clamping and defoaming. No additional drive equipment is required, simplifying the structure and reducing energy consumption. The clamping force can be automatically adjusted according to the working conditions. When alternating clamping, it maintains appropriate force to prevent damage. When defoaming, it automatically enhances stability. When the guide plate is not oscillating, it vertically reduces resistance. The two functions can be performed intermittently, adapting to multiple processes such as electroplating and pre- and post-cleaning, improving production efficiency.

[0028] Working principle: When using this device, the parts are first clamped by the bottom of the moving rod 33, and then the electric push rod 2 is used to place the parts into the electroplating tank 1 for electroplating. During electroplating, the motor 5 is started, and the motor 5 slowly drives the rotating shaft 31 to rotate clockwise. When the rotating shaft 31 rotates clockwise, the paddle block 32 will press the inclined surface 315 on the movable block 34. The movable block 34 moves downward, and the frame 314 also pushes the trapezoidal block 37 laterally to both sides. The trapezoidal block 37 drives the moving rod 33 to move, which can make the adjacent moving rods 33 on both sides move away from the parts, thereby canceling the clamping and enabling electroplating of the clamping part. Since the adjacent paddle blocks 32 are misaligned, one of the adjacent moving rods 33 is in the clamping state and the other is in the loose state. Thus, the moving rods 33 alternately clamp the parts, which can effectively prevent the phenomenon of exposed substrate. When excessive bubbles appear during electroplating, the motor 5 rapidly drives the rotating shaft 31 to rotate counterclockwise. As the rotating shaft 31 rotates counterclockwise, the paddle block 32 presses against the inclined plane 316, causing the inclined plane 316, which is fixed to the drive frame 314, to move the drive frame 314 rapidly longitudinally. The drive frame 314 then moves the two trapezoidal blocks 37 and the moving rod 33 together. When the paddle block 32 disengages from the inclined plane 316, the spring force of the second spring 313 causes the drive frame 314 to reset the trapezoidal blocks 37, completing one oscillation. The inclined surface 316, which is slidably connected to the drive frame 314, will not move. The inclined surface 316 on its lower side will move together with the inclined surface 316 on the lower side of the other drive frame 314. The forward and reverse rotation of the rotating shaft 31 can produce different effects. Not only can alternating clamping and oscillation defoaming be controlled by a single motor 5, but it also means that when cleaning parts before and after electroplating is required, defoaming is not required, only alternating clamping is needed. The triggering conditions of the function are distinguished, making it applicable to different processes. Furthermore, since the rotating shaft 31 and the lever 32 rotate rapidly counterclockwise, and due to the non-Newtonian fluid design in the placement groove 310, the trapezoidal block 37 will not move to the sides due to the squeezing of the lever 32 when it moves down, thus ensuring that the moving rod 33 will not loosen the parts during rapid oscillation, and ensuring the stability of the device clamping. Furthermore, when the dial 32 rotates counterclockwise, due to the centrifugal force, the counterweight 35 will push outwards towards the rotating shaft 31 with a larger force. The counterweight 35 will press the trapezoidal plate 36 downwards, so the clamping block 312 will be pressed towards the trapezoidal block 37, and the spring 311 will be compressed. This will cause the clamping force of the moving rod 33 on the parts to automatically increase slightly, further preventing the moving rod 33 from disengaging from the parts during oscillation. When the dial 32 rotates slowly clockwise, because the counterweight 35 has rounded corners, the centrifugal force is small at this time, and the trapezoidal plate 36 will basically not move downwards. This allows the clamping force on the parts to be increased only during oscillation and debubbling, while maintaining normal clamping in other processes, preventing damage to the parts from prolonged large clamping forces. When defoaming is performed by oscillation, the moving rod 33 drives the left rotating rod 73 and the connecting magnetic block 74 to move towards the left fixed magnetic block 75. This causes the rotating rod 73 to rotate the first guide plate 71 clockwise, thus changing the state of the first guide plate 71 from being perpendicular to the moving rod 33 to being tilted, and the second guide plate 72 to be vertical. This allows the water flow to not only flow along the surface of the parts to disperse the bubbles when the moving rod 33 oscillates, but also to flow along the first guide plate 71 or the second guide plate 72 to the clamped part of the parts to disperse the bubbles, preventing the bubbles from being blocked and accumulating at the clamped part, thus enhancing the defoaming effect. When there is no oscillation, the first guide plate 71 remains vertical, so that there is no excessive resistance from the liquid when alternating clamping, reducing costs. Alternating clamping and oscillation can be performed intermittently to ensure the uniformity of electroplating and defoaming.
